Construction of the overhead railway - on the left of the photograph - began in 1889. The first part of the line was opened in 1893. Running from the Alexandra Dock to the Herculaneum Dock, trains ran every five minutes throughout the day and every ten minutes in the early morning and late evening. Although being neither the world's first electric, nor first overhead railway, it was nevertheless correctly and proudly described as 'The First Overhead Electric Railway in the World'. With its watertight decking providing cover along most of the seven miles of its dockside route, however, it eventually and perhaps more aptly became known as The Dockers' Umbrella.
